Veteran journalist Carl Bernstein said Wednesday afternoon that he believes internet news mogul Matt Drudge was largely the reason Donald Trump was able to capture the Republican nomination for president.

"One of the interesting things we've seen in this campaign is that Fox has driven Trump's candidacy less than Matt Drudge," Bernstein said on CNN. "That Drudge is really the great new factor in this election, in terms of media."

"Drudge — that site has been unapologetically in Trump's pocket from the beginning," he continued. "And I would say that a large measure of why Donald Trump is the nominee goes to Matt Drudge."

Bernstein added that he believed Drudge's influence is "unequaled" in the media.
